HOT-AIR ATTACHMENT TO GOOKING-S'IOVES.

The Schedule referred to in these Letters Patent and making-part ofthe-same.

To all whom it may concern Be it known that I, J OHN NORRIs, of MountPleasant, in the county of Frederick, and State of Maryland,

have invented a new and improved-Heating-Attachment for Stoves; and I dohereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the accompanying drawings, makinga part of thisspecification, in which g Figin'e 1 is an outline sectional view,showing the construction of the stove to which my invention is commonlyapplied.

Figure 2 is a ment attached.

Figure 3 is adetached view, showing the collar and cap.

Figure 4 is a view of 'my improvement, as applied to a commoncooking-stove.

This invention is an improvement upon the tenplate stove, oven-doors ofthe same with a bay, from the top of which projects a short tube orcollar, which conveys heated air to the upper apartments of the house,by means of suitable pipes, and also, when the pipes are removed, servesfor certain culinary purposes, as hereinafter more fully described.

In the drawings, fig. 1 represents a longitudinal vertical section,through the centre of a ten-plate stove, A being the fire-chamber ofsaid stove; B, the oven; B, one of the wen-doors, on the side of thestove; C, the fire-chamber door and air-(haughm' and D, the smoke-flue;the current of air passing from the door side view of the stove, with myimprove- 0 to the flue D, around. the rear end of the oven, as

shown by the red arrows.

The door B is constructed with a deep bay, E, fi'om the top of whichprojects a; short tube or collar, E. A pipe, F, rests upon this tube,and extends to the apartment on the next floor above, being jointed, asat f, in in one or more places, so as to have a slight flexibility. Thispipe is provided with acap, m, to cover its upper end, and another, c,is provided, to cover the tube or collar E, when the pipe isdisconnected from the latter.

When the oven-door is closed, and the pipe F attached, as seen in fig.2,, the hot will pass from the oven to the chamber above.

If the occupants of the and consists in constructing one of the,

bottom of the .bay, when used in this manner. .apparatus could chamberdesire to shut off the draught into their apartment, all they have to dois to place the cap m on the top of the pipe; and if the occupants of.the room in which the stove is 'situateddesire to stop the escape of hotair from the stove to the chamber above, they can at once accomplish itby lifting the pipe off of the collar or tube, the lower portion of thepipe sliding easily in the upper portion by means of the telescopicjoint f. When it is desired to use the oven for the purpose of bakingany article of food, the pipe should be disconnected from the collar E,and the latter closed by the cover or cap, 6.

Instead of c ttaching the bay to the oven-door of a ten-plate stove, itmight be made with a flange, r, as

seen in fig. 4, and be used in connection with the commoncooking-stoves, being bolted through the fiange to their rear side,under the stove-pipe. A register, 8, for the purpose of supplying air,might be provided in the The thus be applied to any old stove in afarmers kitchen, without the trouble of taking itto a blacksmith to befitted and attached. fact, in the whole invention, is not so My object,in 7 much to improve the method of originally casting the stove itself,as to furmsh a convenientattachment, in

the shape of an attachable aud'detachable sheet-iron oven-door,providedwith a bay, as above described, which caube employed in connection withthe old ten -plate stoves, for people of my vicinity, and which can beas readily af fixed to an old stove inthe kitchen, as 'to a new one atthe foundry.

Having thus described my invention,

What I claim as new, ters Patent, is-

As an attachment to a ten-plate stove, the ovendoor, constructed with abay, E, and collar E, and having connected therewith the pipe F,provided with the caps e m, the whole operating in the manner and forthe purposes, specified.
